Corn Sugar.

[SHIELDS EXILE]

Has anyone, used Karo maize syrup as corn sugar,many beer writersay that dextrose is corn sugar, but it does not give the same flavour as flaked maize? Karo dark corn syrup is from USA and is available in most supermarkets.

Interesting find, but I doubt you'll get a good return for your money. There may be equivalents at lesser cost. It also appears to have added preservative that might impact brewing and is made from genetically modified maize which might influence some consumers.

I believe the dextrose monohydrate sold as brewing sugar is made from maize. I also believe we can for brewing purposes assume that dextrose and glucose are the same. Corn syrup is probably a liquid byproduct from dextrose production from maize.

This is over the top for what you ask, but found it when searching for Hydrol that I'd seen in a closed brewery's logbook. It seems that Karo will be made from some similar byproduct, just as molasses is during sugar refinement.

Maize syrup will give significantly different flavours to flakes maize. Flaked maize is converted in the mash tun to different sugars to maize in a chemical process plant.

It tasts good, and Iwill use the same syrup with my next brew of Double diamond 1054 OG which calls for the same stuff .Theextract you get HB shops , does not have the same taste as maize.

Some Karo contains vanilla extract so read the ingredients carefully. And as a Eric pointed out, preservatives adversely affect yeast.
